Fig. 1


Disk-integrated reflected total flux F (left column), linearly polarized flux Q (middle column) and degree of polarization P (right column) of an ocean planet with a rough, Fresnel reflecting surface (top row) and a planet with a black surface (bottom row) as functions of the phase angle, for various wavelengths. Both planets have a pure gaseous atmosphere and are cloud-free. The wind speed above the ocean is 7 m s−1, and the surface coverage of white caps 0.28%. The black dashed line in the ocean planet plots (top row) pertains to a planet covered by the rough Fresnel surface, with a black surface below, thus without sub-surface ocean, and without atmosphere above.
